SEPARABLE. LEDG ER.

SPECIFICATION forming part of Letters Patent No. 715,184, dated December 2, 1902.

Application filed April 14, 1902.

To all whom, it may concern:

Be it known that I, J AMES FACEY WARNE, solicitor, of the city of Ottawa, in the county of Carleton, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Separable Ledger's; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in that class of lodgers wherein the leaves are removable at pleasure, enabling the leaf or leaves of any accou nt to be added to or transferred at any time; and my invention embodies certain methods of construction of the covers of said lodgers to facilitate the addition or removal of a leaf or leaves, as will be hereinafter described in connection with the drawings and subsequently claimed.

In said drawings, Figure 1 is a vertical cross-sectional View of my device on the line 1 1 of Fig. 3. Fig. 2 is a vertical longitudinal sectional view of my device, taken on the line 2 2 of Fig.3. Fig. 3 is a plan View of my device, the upper plate being broken away at one end to show a sectional View, taken on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of my entire device.

Reference being made to the accompanying drawings, in which similar letters of reference indicate similar parts in all the figures, OD represent two complementary metallic an gle-plates, one of which slides over the other, plate 0 being long enough so that the ends a, which are vertical, fit closely and slide over the vertical ends I) of plate D, and the longitudinal vertical back 0 of plate C fits closely and slides over the longitudinal vertical back 61 of plate D, the whole making the adjustable back and ends of the ledger-binder, and to the horizontal portions of the complementary metallic angle-plates O D are secured the rear ends of the covers A B, having reduced flexible portions K K adjacent thereto.

F represents hollow round sleeves made integral with or secured to the horizontal portion of the metallic angleplate D, which sleeves are adapted to slide and fit closely over posts E of the metallic angle-plate G.

E represents round posts made integral with or secured to the horizontal portion of the metallic an gle-plate O, which posts are adapt- Serial No. 102,927 (No model.)

ed and located to enter the hollow round sleeves F of the metallic angle-plate D.

H and I represent hollow round posts of the same diameter integral with or secured to the horizontal portions. of the metallic angleplates C and D at their longitudinal centers, both of which posts are screw-threaded on the inside, one with a right and the other a left handed thread, to hold and engage with the double-threaded screw-spindle G.

G is the spindle, having at one end from the center a right-handed screw-thread and at the other a left-handed screw-thread fitted to engage and work, respectively, in the corresponding right and left handed screwthreads in the screw-threaded hollow round posts H and I, and the upper portion J of said spindle G is made with a socket or projection, to which a key may be fitted through an opening in the horizontal portion of the metallic angle-plate O to turn said spindle G in either direction in said posts H and Iwhen it is desired to open or close the complementary metallic angle-plates C and D in order to add or remove a leaf or leaves from said ledger. The double-threaded screw-spindle G is of the same diameter throughout, as shown in the drawings, save where it is fitted to receive a key at the upper end J.

I am aware that metallic angle-plates hav- I ing telescoping attachments and screw-spindies to adjust said plates worked by a key and ratchet, also rod and bevel-gears for the purpose of holding leaves together to form a book, have been patented, but I do not claim such construction broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is

1. In a device for holding leaves to form a book the combination with complementary angle-plates G and D, bearing respectively posts E, hollow sleeves F, and hollow posts H and I, screw-threaded inside one havinga right and the othera -left handed thread, of a right and left threaded screw-spindle Gr,

havingat one'end means whereby said spin-.

dle may be turned bya key in either direction in said hollow posts H and I, as and for the purpose shown and described.

2. In a leaf-binding device the combination with plates 0, and D, bent to form the back Signed at Ottawa, this 3d day of April, A. D. 1902.

and ends; posts E; and hollow sleeves F, of hollow posts H, and I, screw-threaded inside, one having a right and the other a left handed thread, and spindle G, having a right and JAMES FACEY XVARNE.

arranged and combined substantially as and CHARLES HERBERT PINHEY, for the purpose hereinbefol'e set forth.
